iPhone game ported to Zune HD in only 12 hours

The Zune wasn't even on the market for a week before an iPhone app was ported over. Foundation42 has announced in a tweet that it only took 12 hours to pull off, too: "From #iPhone game to #ZuneHD game in 12 hours using #MonoTouch and #XNA - http://bit.ly/2O3y6Z - enjoy!"

I watched the video following the link but couldn't tell whether the bad resolution images were present in the live port. I imagine that in a worse case scenario, this is more of a technology/development showcase for porting software and plain images have to be reworked still to fit the different screen ratios.
